WINDMILL.

Application led September 24v, 1921. Serial No. 502,865.k

To all whom t may concern:

Be it known that I,"JoHN B. ALTMAN,

3 whereb energy may bevstored for future use. generally the construction and arrangement of the parts of a windmill to the end that the cost of production may be reduced and the durability of the mechanism increased'.

` :The invention is illustrated, in the accompanying drawings and rwill be hereinafter fully set forth. In the drawings* j l y Figure ,l is a plan view of ay windmill embodying my improvements; v

Fig. 2 is a side elevation with parts, in section of the same;y Y A Y Fig. 3 is .a detail Vsectional viewl on the lineB-- of 1;k 3 Fig. 4 is a detailperspective view of the transmission gearing;V f l. n Y i Fig.- 5 is ardetail -perspectiveview ofthe parts whereby Y the '.motion of the driving shaft is imparted to theplunger of the Pumps i.

Fig. 6 is a detail rperspective. view of the governor disc. y f In the drawings, the reference numeral 1 indicates the tubular casing through which the pump plungerAQ operates and which is supported upon the derrick (not shown) for turning movement in a well-known manner. The tubular easing -1 depends from a platform 3, and upon the said. platform yare mounted standards or bearings 4 of any preferred form in whichthe main driving shaft fisjournaled, the wind wheel 6 being se- Another object of e invention also seeks to improve' cured upon the outer end of the said shaft in theusual manner:V Upon the main drivingshaft 45, I 'mountia mutilated gear 7 which is adapted Vrto mesh with' ay larger mutilated gear` 8 upon a countershaft 9 which is `also journaled in. the'bearingsgi, aswill be readilyuunderstood. Immediately adjacent thefgear 7, a segmentl or mutilated gear l() is mounted upon the main driving shaft 5, and this gear 10 is adapted. to mesh with amutila'ted pinion 11 upon the countershaft'9 immediately adjacent the gear r`8, as shown and as will be ^readily understood. The gears may be fixed upon" the Vrespective shafts inany 'convenient or preferred manner "and in the drawingsl I have yshown spacers 12 upon the main driving shaft between the respective gears andthe adjacent bearings. The gears are so arranged that the operativeportionopf one gear isY in the same position with respect to its shaft as the smoother inoperative portionpf its companion gear so that, when thegears 7 and 8, for instance, are in mesh, as shown "in the drawings,.the gears l0 and l1 will Vbe outofy mesh and vice versa. The parts are A Valso sof arranged that, :when the plunger or piston'rod 2 is moving downwardly, the gears 1() and 11 will be in mesh and theplunger will Vbe moving at 'a relatively high speed, butwhen the plunger'has completed its down stroke and starts upon its lifting or working stroke,`the gears 10 and 11 will ceaseY to mesh and the. gears v'7 and 8 will `simultaneously be brought intoV mesh so that thespeed 'of the plunger will will be4A decreased but thepower exerted through ithe same Vwill be relatively increased. i'

The countersha'ftr 9 extends through 'the inner bearings orv standards '4 and; is equipped with acrankl 13 having a roller` 14 at its outer end which plays in a longieov tudinaljslot, 15 of a lever 16 which is fuly crumed upon a postl7 erected at the edge of the platform 3 so that as the crank rotates the lever will be rocked or oscillated. The slot 15 extends to the freev end of the lever 16 and to the free end ofthe lever the upper end of the pump plunger 2 is pivotally attached so that, as lthe( lever is'` oscillated, the plunger will bereciprocated. ,Y

Upon the platform at the sides of the same, I provide posts or short standards 18 in which `governor rods 19 are slidably mounted. The inner ends of the said governor rods are connected by a cross bar 2t) from which an arm 2l extends,' as clearly shown in Fig. l, the said arm having, a head or bearing' plate 22 at its free end, as shown. A vane Q3 is pivotally mounted upon the platform adjacent the arm 2l and is provided with a lateral arm or bracket 24 which carries a roller 25 at its free end adapted to bear against the head 22, as clearly shown in Fig. l. Springs 26 are coiled around the governor rods 19 and bear at their inner ends against the adjacent posts 1S and at their outer ends against nuts or other adjustable abutments 2T upon 'the rods. Stops 28, which may be nuts threaded upon the governor rods, are carried by said rods and adapted to impinge against the inner sides of the outer posts 18, as shown in the drawings. The outer ends of the governor' rods are normally spaced from the posts 18, and a governor plate or disc 29 is mounted upon and extents between the governor rods, being' equipped at its center withan opening- 30 through which the main driving shaft may pass so that there will he no resistance to the rotation of said shaft offered by the governor plate or disc. At diamet-rically opposite points7 the governor disc is provided-with openings 31 tl'niough which the outer ends of the governor rods extend and lock nuts 32 are mounted upon the governor rods at opposite sides of the disc to be turned home against the saine and firmly secure the disc to the governor rods. The abutments 27 may obviously be adjusted longitudinally of the governor rods and the springs lo be thereby put under any desired tension. Should the wind reach a velocity which would tend to drive the windmill and the pump at an excessive speed and, consequently7 damage some of the working parts, the governor-plate or disc 29 will. be forced inwardly against the tension of the springs 26 and the `governor rods would, of course, be moved longitudinally in their supports and pressure would be exerted through the arm 21 and the head Q2 vupon the vane and the lateral arm 24 of the same so that the vane would be swung toward the position indicated in dotted lines in Fig. l, the result beine' that the entire mechanism would be swung' around in its bearing in the derrick so that the edge of the wheel 6 would be presented to the wind and the motion of the working parts would cease. l

A cable is secured to the vane 2? and extends therefrom to and around a pulley f3/l mounted in an arm 35 projecting from the platform, the cable then passing to and over a pulley 3G mounted upon the platform immediately adjacent the upper end of the tubular casing` l, whence the cable passes downwardly through the said casinav to a point near the ground. If it be desired to stop the operation of the apparatus at any time, a downward pull is exerted upon the cable so that the vane will be swung to the position shown in dotted lines in Fig. l and will be thereby exposed to the force of the wind which will immediately act thereon so as to swing' the entire mechanism about the mountingl of the same in the derrick and present the edge of the wheel 6 to the wind, whereupon the rotation of the wheel will cease.

Between the governor disc 29 and the outer bearings et, I secure upon the main driving` shaft a worm gear 37 which meshes with a worm 3S upon a shaft 259 mounted in bearings 4e() at the upper ends of posts l1 which rise from the platform 2 and are braced by a connecting' strap 42. A pulley L3 .is secured upon the end of the shaft 39 and a belt le is ltrained around the said pulley and around a pulley secured upon a shaft 4G which is mounted in bearings provided upon the platform 2 and is connected with an electric generator 4T so as to operate said generator in any convenient manner. The generator may be of any wellknown type and is illustrated in a conventional manner only. A hood` 4S is provided over the generator so as to protect the same from the weather. The current produced in the generator may be carried over any convenient conductors to a storage battery plant and utilizedto charge batteries for future use or it may be carried directly into electrically driven tools or machinery so as to actuate the same as is obvious. y

From the foregoing description, taken in connection with the accompanying' drawings, it will be seen that I have provided a very simple and compactly arranged mechanism which may be installed at a low cost and which will operate efficiently to drive a pump or other machine; which will generate electric energy very economically, and which will be automatically caused to stop its operation should it attain an abnormal velocity.

lilavingthus described the invention. what claimed as new is:

In a windmill, the combination of platform, a main driving shaft mounted upon the platform and having' a wind wheel secured thereto. means for transmitting inotion from the said shaft to elenients to be driif'en. a governor dise disposed adjacent the wind wheel parallel therewith and concentric with the main driving' shaft, governor rods secured to said dise and extending' therefrom parallel with the main driving' shaft and slidably mounted upon the against the bracket on the vane whereby eX- cessive Wind pressure upon the governor disc will turn the vane to one side and stop the 10 operation of the Wind Wheel.

In testimony whereof` I aix my signature. i
